Objective of this research was to determine the slaughter properties and
carcass composition of carcass sides derived from young cattle of Domestic
Spotted breed, of pre-slaughter weights of 500 (group A) and 600 kg (group
B). Heavier cattle had higher share of kidney fat in carcass, whereas the
share of offals showed no significant differences. Statistically significant
difference was registered only in share of toungue (P<0.05), that was higher
in cattle of group A. Share of extra/premium (tenderloin), I category (round)
and II category (loin, back, shoulder) showed no significant differences
between groups of cattle. Statistically significant difference (P<0.05) was
established in the share of III category carcass parts. Share of forearm and
chest was significantly higher in lighter cattle (3.55% and 7.95%) compared
to heavier animals (2.89% and 6.33%), whereas the share of subshoulder was
considerably lower in group A (6.89%) compared to cattle of group B (9.73%).
Data obtained by dissection of main carcass side parts differed significantly
in regard to the share of muscle tissue in round and belly, that was
significantly higher in cattle of group A (P<0.05). Share of fat tissue
(subcutaneous and intermuscular) was higher in cattle of group B in almost
all carcass side parts, however, statistically significant difference between
groups was determined only in round, back, neck and subshoulder. Also, share
of bones in chest differed statistically significantly (P<0.05) and it was
higher in group A (20.09%) compared to cattle of group B (15.52%).
